Legal Definitions - method claim

A method claim is a specific type of patent claim that protects a process, procedure, or series of steps for achieving a particular result, rather than a physical product, device, or composition of matter itself. Essentially, it describes "how to do something" rather than "what something is." These claims are crucial for protecting inventions that lie in the execution of an action or a sequence of operations.

Here are some examples to illustrate how a method claim works:

• Example 1: A Novel Data Processing Technique

  Imagine a software company develops a unique algorithm for securely encrypting and transmitting data packets across a network. Instead of patenting the software program itself or the hardware used, they might file a method claim that describes the specific sequence of steps involved:

  • Step 1: Receiving a data packet.
  • Step 2: Dividing the data packet into multiple sub-packets.
  • Step 3: Encrypting each sub-packet using a distinct, dynamically generated key.
  • Step 4: Transmitting the encrypted sub-packets over different network pathways.
  • Step 5: Reassembling and decrypting the sub-packets at the destination.

  This is a method claim because it protects the *process* of secure data transmission, detailing the actions performed, rather than a physical device or the final decrypted data.

• Example 2: An Innovative Manufacturing Process

  Consider a materials science company that invents a new way to create a lightweight, high-strength alloy. Their invention isn't just the alloy itself, but the specific manufacturing steps that produce its unique properties. A method claim for this invention might outline:

  • Step 1: Heating a mixture of specific metals to a precise temperature range.
  • Step 2: Introducing a controlled inert gas atmosphere.
  • Step 3: Applying a specific electromagnetic field during the cooling phase.
  • Step 4: Rapidly quenching the material in a specialized liquid bath.

  This claim protects the *sequence of operations* that results in the alloy, making it a method claim. Anyone using this exact series of steps to create the alloy would be infringing the patent, regardless of the specific equipment they use.

• Example 3: A Unique Business Service Protocol

  A startup develops a novel system for personalized online learning that adapts to a student's real-time performance. They could seek a method claim for the interactive educational process, such as:

  • Step 1: Presenting an initial assessment to the student.
  • Step 2: Analyzing the student's responses to identify knowledge gaps.
  • Step 3: Dynamically generating customized learning modules based on identified gaps.
  • Step 4: Delivering the modules and monitoring student engagement and progress.
  • Step 5: Adjusting subsequent module content and difficulty based on real-time performance data.

  This is a method claim because it describes the *steps involved in delivering a service* or an interactive experience, rather than a particular software application or a physical textbook.
